Ahh... Thank you. In 7 years I've never had the need to dig that deep into that area. I likely saw it while pulling the fuel tank to plumb in the aux fuel line but was more concerned with not breaking anything than figuring out what all that stuff was... :grin:The ECU is behind the right side fairing. You loosen the coolant bottle and move it aside. Then you can see the ECU. The Bren website shows a quick video of how to remove it.
